Because the telescopic ring suction plate is close to the pot mouth, and the area of ring suction plate is usually great, causes a large amount of oil smoke to condense into oil drop at the internal surface of ring suction plate easily, and the time of cooking is long, and the oil drop of condensation will be pooled together and drop to the top of a kitchen range, drip into the pot of cooking even, seriously influence use experience. The side-draft range hood disclosed in chinese patent application No. 201320155464.0 (grant publication No. CN 203231365U) has a front panel and an oil cup mounted at the bottom of the front panel, an opening communicating with a smoke collecting cavity of the range hood is provided on the front panel, a smoke guide plate covering the opening and forming a certain interval with the front panel is provided outside the opening, and an oil guide plate is provided between the smoke guide plate and the oil cup. Although the greasy dirt on the smoke guide plate can enter the oil cup through the oil guide plate, so that the greasy dirt is prevented from directly dripping onto the cooking bench from the bottom of the smoke guide plate, the smoke guide plate is fixed and cannot move, so that the negative pressure area cannot expand downwards, and the effect of sucking the greasy dirt is limited.
Therefore, as disclosed in chinese patent No. CN201621014012.0 (issued to the public No. CN 206073187U), the smoke machine includes a smoke collecting hood, a smoke baffle and a smoke baffle translation device, the translation device includes a sliding rail, a sliding block embedded in the sliding rail and capable of moving along the sliding rail, a link mechanism pushing the sliding block, and a push rod motor, the front end of the sliding block is fixedly connected with the smoke baffle, the rear end of the sliding block is connected with the link mechanism, the push rod motor drives the sliding block to move and further push the smoke baffle to open and close in a translation manner through the link mechanism, the smoke baffle (smoke baffle) can be automatically opened when in use, and can be automatically closed after use, so that the smoke smell of smoke is effectively prevented, and the effect of smoke absorption is improved. In order to solve the problem, part of products in the market at present are provided with a drainage groove at the lower edge of the annular suction plate to guide condensed oil back to an oil cup of the smoke machine, but the annular suction plate in the form is made to be fixed and can not stretch; some products can make the ring suction plate movable so as to retract to be level with the front panel when not cooking, so that the appearance is more attractive and the treatment is more convenient, but the lower edge of the ring suction plate is limited by the structure and can not be provided with the drainage groove, so that the oil dripping problem of the ring suction plate can not be effectively solved when cooking. Therefore, the prior ring suction plate type range hood has the following two problems on an oil way: 1. when the ring suction plate is made into a movable telescopic type, condensed oil on the ring suction plate can be dripped on a cooking bench or a pot during cooking; 2. the ring suction plate type range hood without oil dripping has the advantages that the ring suction plate is fixed, cannot retract in a non-cooking state, influences the beauty and is inconvenient to manage.
